ABSTRACT KEYWORDS

In China, the poor supply logistic and the high feedstock cost are the Supply logistics; most critical constraints to the development of forest bioenergy. The aim Bioenergy; of this study is to identify the supply logistic from forest land to the final Forest; delivery for bioenergy utilization. A case study approach was used to Case study; collect the relevant information and data. And two different supply logistics China. of wood biofuel were designed for two locations in , one was from collective forests and the other was from state-owned forests.  2013 Trade Science Inc. - INDIA

More than 110 000 tonnes of wood fibre is currently used for household heating and cook- ing annually. Per capita wood fuel consumption is higher in Arxan than Naimanqi because wood is more easily available from wood processing plants and wood fuel collection. This leaves sufficient potential forest biom- ass for the proposed bio-power plant.

est biomass collection was carried out, the number of collection sites and the type and size of equipment used. A significant result of the study is that a shorter collec- tion distance, a more simplified division in work and more larger-scale equipment was incurred in Naimanqi than Arxan. Based on the assumption of using the exist- ing equipment in the Arxan case, more equipment and fuel would be consumed in the hauling process. At present, commercial bioenergy from forest bio- mass is still in its infancy in China and little case data is available to compare with the supply logistics in Arxan and Naimanqi. So there are still some uncertainties in the evaluation of forest biomass use for bioenergy.
